Method of reading data stored in a data storage device and data storage device that performs a data read retry operation

A disk drive includes a disk having a track that includes a data sector divided by a servo sector so that a first data sector portion is on a first side of the servo sector, and a second data sector portion is on a second side of the servo sector. The disk drive reads data by: positioning the head at a first offset position with respect to the track and reading data from the data sector. When a read error occurs between the first and second data sector portions, the disk drive: stores the data from the first data sector portion in memory, moves the head to a second offset position with respect to the track, reads data from the second data sector portion with the head at the second offset position, and stores the data read from the second data sector portion in the memory.
